Hey everyone,
So my most recent purchase was a vintage Marshall JCM800 1960 4x12 cabinet with Celestion 75s in it (for $300!) and it rocks with my Marshall head. Unlike other cabinets I've owned, the Marshall cab only has one input for one head to plug into. Would there be a way I can split that and plug 2 heads (If I bought another) into the cabinet and A/B the heads with a pedal, or would I just have to buy another cabinet for that and plug the other head into that? Thanks

I would just rewire the cab to run stereo with an A/B switch. Since the Headbone isn't a loadbox, you can't run delay in the effects loop though. Anything that's still sending a signal in the effects loop (directly into the power amp) when you switch isn't going to be a good idea, you'll mess up the Headbone, your amp, or both. I think you could make sure everything is off before you switch? The manual says don't use anything in the FX loop though. I'm not sure all the details but when I was looking into one I just screw it and saved myself the money.

That said, if you don't use anything in your FX loop, go for it. I just think that thing is way expensive when you could simply rewire your speakers.

Hit the footswitch and the Headbone toggles the guitar signal from one amp to the other, disconnects the speaker and diverts the signal to a load resister, reconnects the speaker to the second head and turns on the guitar, all in quick succession. The Headbone features SafeMode™ whereby even when power is disconnected; the Headbone will automatically default to 'head-1 to cabinet' status, ensuring a constant load on the amplifier.
